FIREPROOF PARTITION.

Specification of Letters Patent.

Patented July 13, 1915.

Application filed April 11, 1914. Serial No. 831,150.

the city and county ofDenver and State of' Colorado, have inventedcertain new andl useful Improvements in FireprooitI Partitions; and I dodeclare the following toibe a full, clear, and eXact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the letters and figures of referencemarked thereon, which form a part of this specification.o

My invention relates to improvements in fire proof constructions aspartitions, Walls and ceilings vand comprises a special constructionxofmetal stud together with means for securing a suitable sheeting thereto.The stud and fastening means employed therewith are more especiallyintended and adapted for use with plaster boards of the various kindsutilized in the construction of partitions of the character indicated,though it is evident that my improvement may be combined with sheets ofany other character.

The invention in its simple or fundamental form, consists of a metalstud having a part passing transversely between the adjacent edges ofothe sheeting, as plaster board sections, prongs or projections beingpunched out of the web or transverse porf tion of the stud for 4thepurpose of engaging the plaster board sections on one side, whilesuitable means may be employed in connection with the stud for'engagingand supporting the plaster board sections of the partition on theopposite side. Various devices may be used on the opposite side of thesheeting from the prongs or projections. The web or transverse part ofthe' stud may have a slot inclined to the vertical direction of thestud, and adapted to receive keys which, as they are moved downwardly inthe slots, act upon the plaster board or other sheeting sections by awedging action. Other means, however, may be resorted to, aswedge-shaped keys or nails inserted 1n holes in which they lit, theholes being so arranged that as the keys are inserted and driven intoplace, theyL secure the plaster spaced to engage the sheeting sectionson both sides. It will be understood that these prongs or projectionswhich are punched out of the stud are arranged in dilerent verticalplanes and are caused to extend in opposite directions from the web ofthe stud, whereby they embrace and support the adjacent sections of thepartitions on both sides of the stud. Other forms of construction willbe explained as this specification proceeds.

Having briefly outlined my improved construction, I will proceed todescribe same in detail, reference being made to the accompanyingdrawing, in which is illustrated an embodiment thereof.

In this drawing,-Figure l is a fragmentary side elevation of a sectionof a plaster board partition constructed ,in accordance with myimprovement. Fig. 2 is a Vertical section taken through the same on theline 2 2, Fig. 1. Fig. 3 is a perspective View illustrating one form ofmy improved stud, the plaster board sections employed therewith beingindicated by dotted lines. Fig. 4 is a section taken through the plasterboard portion of the partition, viewed in the directionof the stud,which is of the construction shown in Fig. 3. Fig. 5 is a horizontalsection taken on the line 5 5, Fig. 1, looking downwardly. Fig. 6' 85 isa section similar to Fig. 5, but showing a modified form of fasteningmeans for the plaster board sections on the opposite side from theprongs carried by the stud. Fig. 7 is an elevation of the form ofconstruction shown in Fig. 6. This view will be obtained by looking inthe direction of the arrow 7, Fig. 6. Fig. 8 is a perspective view of afiat stud showing prongs punched out of the same and extending inopposite directions from the body ofthe stud, the outer extremities ofthe prongs being hooked shaped. Fig. 9 is a View of still another formof stud, the same being adapted for use where double partitions areemployed to forma hollow wall. Figs. 10, 11, 12 and 13 are sectionssimilar to Fig. 6, but illustrating other forms of construction, thesefigures relating- Fig. 14 is a perspective view of still another form ofstud, in which projections punched out of the transverse portion or webof the stud are employed for maintaining the sheeting sections in placeon both sides. Fig. 15 is a horizontal section similar to Figs. 10 to13, inclusive, showing still anotherl form or embodiment of theinvention. Fig. 16 is a section illustrating my improvement applied atthe corner of partitions where the two partition members are arranged atright angles to each other. Figs. 17 and 1S are top plan viewsillustrating other forms or embodiments of the invention.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate one form of my improved metal stud, the samebeing channel shaped and having a web 6 adapted to. pass transverselybetween the adjacent edges of the section 7 of the sheeting, while theflanges 8 give strength and rigidity to the stud. Out of the web 6 ofthe stud are vpunched prongs or projections 9, which extend from the webof the stud in opposite directions, the said prongs being located atdifferent elevations and lyingbetween the Same vertical planes. Theseprongs are so arranged that they are adapted to closely engage theplaster board sections 7 on one side when the sections are brought intoproper coperative relation with the stud for partition purposes.Suitably spaced transversely from the prongs 9 is a slot 10 also formedin the web or transverse part of the stud, and so arranged that when akey, as a 'lat piece of metal 12 is inserted in the slot and moveddownwardly, it will engage the plaster board sections 7 on the oppositesides from the prongs or projections 9, by a wedging action. In thiscase, the upper extremity of the inclined slot is farthest outwardlyfrom the partition sections, and the slot extends inwardly toward theplane of the adjacent surfaces of these sections. the length of the slotbeing such as to permit the desired range of adjustment of the key forsecuring purposes.

It is evident that instead of integral prongs 9 punched out of the webof the stud as illustrated in this and other views showing diierentJforms of construction, separate prongs or projections, as nails, mightbe driven into openings Jformed in the web of the stud and caused toproject therefrom in the same manner and adapted to perform the samefunction as the integral 'I prongs. The prong form is, however,preferable, inasmuch as this construction is cheaper and is believed tobe better for the purpose intended.

From what has just been explained, the manner of constructing apartition of the character indicated where the form of stud justexplained is employed, will be readily understood. The studs arearranged at snitable intervals depending on the width of the partitionsections 7, the studs in the ordinary vertical partitions beingvertically arranged endwise between upper and lower sills or supports 13and 14. Assuming that the prongs 9 are employed, the partition sectionsare placed edgewise against the webs G of the studs and so that the saidprongs engage the adjacent sections on one side. The keys 12 are theninserted in the slots 10 and forced downwardly against the partitionsections on the opposite side, whereby the sections are held securelyin'place. As illustrated in the drawing, the top and bottom supports 13and 14 are mortised to receive the opposite extremities of the studs. ltis evident, however, that the studs may be secured in any other suitablemanner.

In the form of construction shown in Figs. 6 and 7, a U-shaped clip 15is employed instead of the slot and key disclosed in Figs. 1 to 5,inclusive.v This U-shaped clip is closed at one end as shown at 16,where it passes outside of one of the flanges 8 of the channel bar stud5. From the eX- tremities of the part 16, the parallel arms 17 of theclip pass transversely between the partition sections 7, their freeextremities being bent outwardly to engage said sections on the oppositeside from the prongs 9.

In the form of construction shown in Fig. 8, the stud is flat or lies inAa single plane. This form of stud may be designated by the numeral 19.Prongs 19 are punched out of the stud and extend in opposite directionstherefrom, whereby they are adapted to engage the partition sections 7in the same manner as the other forms of prongs, eX- cept that theprongs 19 are oiset or hooked shaped at their outer extremities as shownyat. 20, whereby they may be caused to slightly indent the adjacentsurfaces of the partition sections, (see Fig. 10).

In Fig. 9 a stud is disclosed consisting of a flat bar of metal 21,having prongs 9 punched therefrom in opposite directions, there beingtwo sets of these prongs which are suitably spaced to support partitionsections on the inside where a hollow w-all is to be constructed. Inthis case, the transverse space between the two sets of prongs 19 is,the width of the space between the two members constituting the doublewall. The opposite side edges of this stud are provided with slots 22,which are inclined downwardly and inwardly in the direction of thesheeting. The upper extremities of these slots are open to receive keysadapted to engage the sheeting by a wedging action when the keys aremoved downwardly in the slots.

In the form of construction shown in Fig. 10, the form of studillustrated in Fig. 8 is employed, but the partition sections 7 are heldin place on the side opposite from the prongs 19, by T-shaped springclips 23, which as shown, are formed from an integral piece of springmetal having a part 24 extending parallel with the adjacent surface ofthe sheeting. At the outer ends of the part 24, the metal is bentonitself and carried inwardlyftoward the stud, as shown at 25, ,where itis again bent as shown at 26 and terminates in spring arms 27 adapted topass between the adjacent edges of the plaster board sections, andtightly engage the flat bar stud on opposite sides. This clip is forcedupon the stud and into col' Operative relation with the plaster boardsections in a manner that will be readily understood when it isexplained that the parts 27 are under tension, their free extremitiesbeing curved slightly away from each other to facilitate the applicationof the clip to the outer edge of the stud. Then as the clip is forcedinwardly toward the partition, the spring arms will be separated andplaced under tension to tightly embrace the body of the stud, while theexterior portion of the clip will engage the plaster board section 7 onthe opposite side from the prongs or projections 19.

The form of construction shown in Fig. 11 is substantially the same asthat shown in Figs. 1 to v5, inclusive, except that a wedge shaped nailor key 28 is inserted in an opening formed in the web 6 of the chan` nelbar stud 5, to receive the key or wedge shaped nail which is driventhereinto, whereby it is caused to tightly engage the sections 7 of theplaster board on opposite sides of the stud.

In the form of construction shown in Fig. 12', a T-shaped stud isemployed, the prongs 9 being punched out of the web 29 thereof to engagethe plaster board, sections on one side, while the flanges 30 of thehead of the stud engage the said sections on the opposite Side. c

In the construction shown in Fig. 13, the form of stud illustrated inFig. 14 is employed, consisting of. a channel bar 31 having two sets ofspaced projections, one set' being designated 32 and the other set beingdesignated 33. The partition sections 7 are inserted between these twosets of projections, which are suitably spaced for the purose. f

p In the form of construction shown in Fig. 15, a flat stud 34 isemployed, having prongs or projections 35 extending therefrom onopposite sides and each providedawith a series of teeth 36, adapted4 toindent the adj a cent surfaces of the plaster board. sections; while onthe opposite side, a key 12 is employed. v

In the form of construction shown in Fig. 16, the plaster board sections7 are arranged at right angles to each other and the channel stud 37 isplaced at the corner, the web 38 passing diagonally between the beveledad@ jacent edges of the partitions Prongs 39 are punched out of the weband bent in directions parallel with the right angularly arrangedpartition sections, these prongs being connected' with the sections bywire loops, whose arms are passed through the partition sections andsecured by twisting their extremities, as shown at 40.

In the form shown in Fig. 17, a flat bar 'stud 41 is employedv andprongs 42 are punched therefrom in such a manner that the prongs must bebent outwardly in order to engage the adjacent surfaces of the partitionsections 7. In bending them out, they are also given a half twist asshown at 43, whereby their edges engage the plaster board sections. Onthe 'opposite side the form of key 12 is disclosed. Y

In Fig. 18, the construction is substantially the same except that theprongs are given a quarter twist as shown at44, instead of a half twist,as disclosed in Fig. 17. Hence, in Fig. 18, the flat sides of the prongsor projections are in engagement with the adjacent surfaces of theplaster board sections.

From the foregoing description, the manner of installing partitionsembodying my invention will be readily understood and neednot bedescribed in detail. It is evident that the metal stud carrying orprovided with prongs extending from the part thereof occupying atransverse position with reference to the sheeting, regardless of theform of the stud in other respects, is the primary or fundamental ideaof the invention, since various other Vmeans or devices may be employedfor securing the sheeting on the side opposite that engaged by the Ksaidprongs; while it is preferred to employ may be employed as indicated inthe drawings and still others will readily occur. v My only object is toindicate in a general way a few of the possible constructions that maybe employed without departing from the invention. j

Attention is called to the fact that while the term partitions has beenmore particularly referred to as the structure with which my improvementis adapted Afor use, it must be understood that this term is ofsufficient scope to cover walls of all character, as ceilings, floorsand outside walls, as well as walls of the character usually termedpartitions. Furthermore, while in the construction as disclosed, the,prongs or projections with which the studs are equipped are arranged inlongitudinal alinement, which of course, is the preferred form and infact, the form which will in most cases be employed, it must beunderstood that a construction is clearly within the scope of theinvention in which these prongs or proj ections are staggered, or out oflongitudinal alinement. In some cases, the peculiar construction of thewall or partition may require such staggered arrangement of the prongs.
